  1. NIKHEF site report What’s new at NIKHEF’s infrastructure and Ramping up the LCG tier-1 Wim Heubers / NIKHEF (+SARA) HEPix April 2006

  2. What’s new at NIKHEF’s infrastructure Servers & desktops • Server systems: • Supermicro: SLC3, SLC4, MS Server 2003 • high-end file service: EMC • low-end file service: Supermicro + Infortrend • compute server: quad Opteron(theory dep.) • Desktop systems: • Dell Dimensions: SLC3, SLC4, MS XP • Apple Mac revival HEPix April 2006 Wim Heubers / NIKHEF

  3. What’s new at NIKHEF’s infrastructure Migrating file services • Phasing out Solaris (NFS) and MS 2003 (CIFS) central file services for ‘home’ and ‘project’ • Migration to EMC NS502 filer • Integration of Unix and Windows home dirs • native NFS and CIFS access (no SAMBA) • different view on same file • Advantages: • one home dir per user, one quota system (incl group), snapshots, dynamic volume management, etc. HEPix April 2006 Wim Heubers / NIKHEF

  4. What’s new at NIKHEF’s infrastructure Storage on demand • SARA(1) offers ‘storage-on-demand’ • iSCSI, NFS, CIFS services • high (FC) and normal (SATA) performance • implemented on EMC • connection: dedicated fibers (or OPN, or VLAN) • pilot project has just started • exploring data migration scenarios, replication and backup issues, etc • fixed price per TB/year for 3-years contract. (1) SARA is our neighbor and ‘partner for a broad range of expertise in ICT’. HEPix April 2006 Wim Heubers / NIKHEF

  5. What’s new at NIKHEF’s infrastructure Networking • Upgrade NREN (SURFnet-6) connection: • 10 gigabit/sec bandwidth • OPN services • we are ‘pilot user’, good results! • Wireless LAN Eduroam authentication • inter-institutional roaming • RADIUS-based infrastructure that uses 802.1X HEPix April 2006 Wim Heubers / NIKHEF

  6. Ramping up the LCG tier-1 Netherlands LHC/Tier-1 • Partners: NIKHEF, SARA, NCF • Budget: BigGrid (the Dutch E-science Grid) • Organization: to be discussed • Network infrastructure present at campus: • NREN SURFnet-6 core • The Amsterdam Internet Exchange ams-ix • The optical internet exchange Netherlight HEPix April 2006 Wim Heubers / NIKHEF

  7. Ramping up the LCG tier-1 Netherlands LHC/Tier-1 • Commitment share of total Tier-1 needs: • LHCb: 23% • ATLAS: 11,5% • ALICE: 5,75% • Planned resources: reminder: update power & cooling infra HEPix April 2006 Wim Heubers / NIKHEF

  8. Ramping up the LCG tier-1 Netherlands LHC/Tier-1 • Service challenges • VOBox discussion • Security infrastructure • 3D database project HEPix April 2006 Wim Heubers / NIKHEF

  9. Ramping up the LCG tier-1 Current resources: clusters • LCG2 production cluster • 66 nodes, dual AMD 1.6 GHz (home made, heat!) • 30 nodes, dual Xeon 2.8 GHz (Supermicro) • 32 nodes, dual Xeon 3.2 GHz (Dell) • LISA – Dell ‘national’ cluster, partly available for LCG) • 625 nodes, dual Xeon 3.4 GHz • Matrix – IBM cluster • 36 nodes, dual Xeon 3.0 GHz In progress: purchase 100 dual Xeon nodes HEPix April 2006 Wim Heubers / NIKHEF

  10. Ramping up the LCG tier-1 Current resources: storage • Mass storage system distributed on two locations • Amsterdam and Almere (‘a booming city in the polder’) • Hardware: • Disk cache on 5 nodes, 2 TB/node • 2 StorageTek tape robots (STK 9310, STK SL8500) • Fibre Channel SAN • Software: • SRM and dCache • CXFS and DMF (SGI) data migration to/from tape • LCG storage now: 40 TB (permanent) + 20 TB (volatile) In progress: purchase 24 TB durable storage HEPix April 2006 Wim Heubers / NIKHEF

  11. Thank you HEPix April 2006 Wim Heubers / NIKHEF
